Question

Question 16 A 220 V line supplies a total current of 5A to a total number of N resistors
each of 176ohm) connected in parallel. What is the value of N?​

Answer 1

Answer:

4 resistors are connected in parallel

Explanation:

we know that

R = V/I

so Net resistance = 220/5 =44 ohm

so N resistors of 176 ohm are connected in parallel to give 44 ohm net resistance.

therefore, in parallel combination

44 = 176/N

then N = 176 / 44

N = 4

hence, 4 resistors of 176 ohm are connected in parallel
